Sheffield United boss David Weir is unsure about Manchester United watching Harry Maguire.
The young defender is being linked with a January move to Old Trafford.
Weir told Sky Sports: "I don't know anything about it, but it is great news for our players to be linked with such big clubs.
"Harry has a lot of attributes, for a young lad he has played a lot of games, and I would not be surprised if clubs were looking at him.
"But we don't want to lose him."
